CORN-SHELLER.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed August 16, 1907. Serial No. 388,875.

To all whom it may concern:

Be it known that I, WILFORD H. HoLs- CLAW, a citizen of the United States, residing at Louisville, in the county of Jefferson and State v of Kentucky, have invented certain new and useful Im rovements in Corn- Shellers, of which the Following is a specification.

My invention relates to improvements in corn shellers.

The object of my invention is to provide a corn sheller which will be simple 1n construction, cheap to manufacture and effective in operation.

The invention consists of the constructions and combinations of parts hereinafter described and set forth in the claims.

In the drawings, Figure 1 is a vertical sectional view of a device embodying my invention. Fig. 2 is also a vertical sectional view of the same showing in additionthereto adjusting means, some of the parts also being broken away. Fig. 3 is a detail of the adjusting means referred to.

Like parts are represented by similar characters of reference in the several views.

In the said drawings, (t represents the main frame of the sheller having an upper hop er, a and a hub, o b is the usual toot .ed shelling disk mounted upon a shaft, b", with the shaft projecting from the toothed or front face of the disk, and revolubl mounted in the hub, a said toothed disk being adapted to cooperate with the ribbed face of the hopper to effect the shelling operation in a wellknown manner.

In corn shellers of this character, means are provided for holding the toothed rotating disk in yielding relation with the ribbed face of the hopper to permit the parts to yield with reference to each other when an ear of corn passes therethrough, a s pring being provided for this purpose; 'In my improved device,,I have so arranged this spring that the device will present a neat appearance, and the parts be less liable to get out 'of order. To accomplish this ,I have provided the hub, a with an enlarged portion or chamber and have inserted within this chamber about the shaft, F, a spring, 0.

t represents the crank for the purpose of rotating the disk, 1), shown in Fig. 1 as screwthreaded upon the shaft, 6 although if desired the crank can be secured upon said .3 shaft by a set-screw in a well-known manner,

the shaft, 6 projecting for a suitable distance beyond the hub so as to permit the necessary movement between the crank, 6 and the end of the hub, to permit the yielding of the disk, I), with reference to the hopper, a Located on the shaft, 6 between the spring, 0, and the crank, U2, is a loose sleeve, (1, which when the disk, I), and the hopper, a are in normal relation to each other will project partly within the hub, a and form a bearing for the shaft at this end of the hop )er. By this construction it will be seen that the tensioning spring, 0, is located entirely within the hub, (1 and the pressure on the spring is central and consequently the spring cannot get out of order as many other sheller springs do, besides presenting a neat and attractive appearance.

In Figs. 2 and 3 I have shown adjusting means for the tensioning spring. In this construction the crank, N, is not screwthreaded upon the end of the shaft but is adapted to be keyed thereon so as to be movable upon the shaft in a longitudinal direction, the shaft, 19 being provided with a projecting pin, b adapted to fit a slot, 6 in the crank d; the shaft being screwthreaded at its end and provided with a locking nut, 5 to secure the crank thereon, and furnish the means for adjusting the tension of the spring 0. The crank in this case may be formedfrom sheet metal and be provided with an auxiliary slotted portion, I)", and an opening, adapted to receive a bolt, 5 to as sist in further clamping the cranlgnrpon the shaft.

Although I have specifically described the construction and relative A, arrangement of the several elements ofnriy invention, I

not desire'to be confinedto the same, as such changes or modifications may be made as/"" clearly fall With'n the scope of my invention without departing from the spirit thereof.

Having thus described my invention, I claim- 1. In a corn sheller, a main frame having a hub, a rotatable shaft located. in said hub having a shelling disk thereon, a s ring located about said shaft .within sai hub, a crank for said shaft, and a loose sleeve on said shaft between said crank and said spring disconnected from and freely movable with gafgrence to said hub, substantially as speci- 2. In a corn sheller, a main frame having a hub, a shaft located in said hub having a shelling disk thereon, said hub being provided with a chamber about said shaft, a spring located in said chamber, a crank on the end of said shaft, and a loose sleeve 011 said shaft between said crank and spring located partly Within said chamber but disconnected from and freely movable With reference thereto, substantially as and for the purpose specified.

3. In a corn sheller, a main frame having a hub, a rotatable shaft located in said hub having a shelling disk thereon, a spring located about said shaft Within said hub, a crank for said shaft, a loose sleeve about said shaft between said crank and said spring disconnected from said hub and freely movable With reference thereto, and means for adjusting the tension of said spring, substantially as specified.

4. In a corn sheller, a main frame having a chambered hub, a rotatable shaft located in said hub having a shelling disk thereon, a spring located about said shaft Within said hub, a crank on the end of said shaft, and a longitudinally slidable sleeve on said shaft between said spring and crank and held in position thereon by said crank, substantially as specified.

In testimony Whereof, I have hereunto set my hand this 23rd day of July, 1907.
